The Acceleration of an object is given by a(t)=6sin(t) with initial velocity of -9.5(v(0) = -9.5). Find the distance the object travels on the interval [0,pi] to the nearest integer.

I was able to take the integral of the acceleration to get it to the velocity and I found C(the number that when you take the integral it ends up at the end) but I am not sure how to continue. I assume you take another integral but I am not sure.

Could you please explain?
